Aim: To assess the feasibility of ambulatory surgery in the treatment of benign prostatic hyperplasia using radio frequency (TUNA) and evaluate its place in terms of efficiency among other minimally invasive surgical techniques.
Method: Fifty-four patients suffering from benign prostatic hyperplasia and for whom medical treatment was ineffective, were treated with radio frequency between September 2004 and June 2007. Among them, 28 patients, whose average age was 65.8 (aged 52-82), were selected for Transurethral Needle Ablation (TUNA) as outpatients. Urine status was assessed before and after TUNA treatment using the International Prostate Score System, the Quality Of Life-score to urinary symptoms, the measures of the maximal flow rate and of the residual urine. The erectile function was assessed using the five-item version of the International Index of Erectile Function (IIEF-5).
Results: With an average regression of 12.14 months, a significant improvement in urine status was observed with an average IPSS score passing from 22.4 to 9.75 and an average quality of life score passing from 4.9 to 1.9. The maximum flow rate and average flow volume increased significantly from 8.66 to 14.6 ml/s and from 202 to 248.4 ml respectively. Average urine residue was reduced from 177.4 to 112.2 ml (p<0.05). The IIEF-5 score did not increase significantly (14.1 versus 12.8). There were no cases of patients being rehospitalised. One case of prostatitis and six cases of acute urinary retention were observed at the postoperative stage. The rate of retreat was 21.4%.
Conclusion: TUNA treatment is a minimally invasive technique of benign prostatic hyperplasia which can be carried out in ambulatory surgery and which is effective for urinary symptoms with little risk of morbidity. It is an alternative to medical treatment and does not replace planned surgical treatment.

Aim: To investigate the predictive value of lesion length in multiparametric prostate magnetic resonance imaging with respect to prostate volume for clinically significant prostate cancer diagnosis in targeted biopsies.
Materials And Methods: The data of biopsy-naïve patients in the Turkish Urooncology Association Prostate Cancer Database who underwent targeted prostate biopsies were included in this study. Lesion density is calculated as the ratio of lesion length (mm) in MR to prostate volume (cc).

Background: The causal associations and potential mechanisms between prostatic diseases, the predominant male urological disorders, and the course of COVID-19 remain unclear.
Methods: A two-sample Mendelian randomization (MR) analysis was performed to evaluate causal associations between prostate cancer, benign prostatic hyperplasia, and prostatitis and different COVID-19 outcomes (SARS-CoV-2 infection, hospitalized COVID-19, and severe COVID-19). Reverse MR, linkage disequilibrium score regression, and Bayesian colocalization analyses were subsequently performed to strengthen the identified causal relationships.

Background: Speckle-type POZ protein (SPOP), FAS-associated protein with death domain (FADD), and nuclear transcription factor-κB (NF-κB) have been shown to be associated with the development of prostate cancer (PCa). FADD has been shown to activate the NF-κB pathway to promote tumorigenesis, while SPOP has been shown to enhance the breakdown of FADD and inhibit the function of the NF-κB signaling pathway in non-small cell lung cancer. The existence of this mechanism has not yet been confirmed in PCa.

Background: Aggressive angiomyxoma (AAM) is a rare benign mesenchymal tumor known for its aggressive behavior and high recurrence rates, with male cases of AAM being less frequently reported. This study presents a rare case of primary prostatic AAM characterized by a prostatic urethral mass obstructing the bladder outlet, resulting in acute renal dysfunction.
Case Description: The 51-year-old male patient presented with lumbar pain, nausea, frequent urination, urgency, and incomplete urination.

Background: The global prevalence of lower urinary tract symptoms suggestive of benign prostate hyperplasia (LUTS/BPH) escalates, with obesity recognized as a major contributing factor. However, the association between the relative fat mass (RFM) and LUTS/BPH remains unexplored. This 7-year follow-up study aimed to investigate the cross-sectional and longitudinal relationships between RFM and LUTS/BPH.
